In order to enhance the resolution of Charge Coupled Device (CCD) pixel with the pixel dimension and focal length of optical system unchanged
the problem of CCD geometric superresolution is educed. The problem is discussed in terms of software and hardware. In software
the bicubic interpolation is introduced
while in hardware
the subpixel imaging method is utilized. The subpixel imaging method integrates two uniform linear CCDs staggered by half dimension of pixel in one device. In operation
the line frequency is doubled. At last
the collected data is interweaved to synthesize a high resolution image. The two methods
bicubic interpolation and subpixel imaging
are simulated with Matlab7.0.1. The qualitative and quantitative analyses are given. The simulated results of lanczos and cubic spline interpolation methods are given simultaneously to show the performance of interpolation. The simulation result shows that the result images quality becomes better in both methods
but compared with bicubic interpolation method
the synthesized image PSNR gained from sub-pixel imaging is averagely enhanced by 2.1682dB
while the elapsed time is reduced to be about one forth. The subpixel imaging method could significantly mitigate the image blur introduced by undersample. 2009 IEEE.
